4. The First Time The Justice League Teams Up (Justice League Part One)
The Moment: The first time the full Justice League line-up converges to take on whatever mammoth enemy is coming their way. When It Will Happen: Likely in the third act of Justice League Part Two, when there will surely be nobody left to introduce into the line-up (Green Lantern and Flash might be a little late to the party), and the team needs every member it can rustle up to bring down the big bad. Why It Will Define The Movie: When you think of the original Avengers movie, what's the first image that enters your mind? There's a good chance that it's that awesome panoramic shot of the Avengers looking totally bada** during the Battle of New York, right? Without wanting to just rip-off the MCU formula, that's the sort of thing this moment needs. Sure, it can be grittier and darker, but it needs to look just as bada** and cement that this is one of the greatest things to ever happen to comic book cinema.
